To all whom it may concern:

Be it known that I, ANTONIO J. (knows, a citizen of the United States, residing at Jacksonville, in the county of Duval and State of Florida, have invented certain new and. useful Improvements in Gaseous-Fuel Mixers, of which the following is a specification. h

This invention has relation to fuel vaporizing devices and the nature and objects thereof will be readily apparent to those skilled in the art to which it appertains in the light of the following explanation of the accompanying drawings illustrating What I now believe to be the preferred embodiment, or mechanical expression,of my invention from among other forms and arrangements within the spirit thereof or the scope of the appended claims.

However, an object of the invention is to provide a device adapted for interposition between the carbureter and intake manifold of an internal combustion engine whereby, kerosene oil may be employed as fuel and fed to the carbureter to be vaporized thereby to the extent to which the carbureter is capable of vaporizing this type of fuel, and whereby the vaporized oil may, upon passing through the device be subjected to further treatment to homogenize the vapor permitting the product to be ignited in, the cylinders of the engine with the production of less carbon or other undue waste prod ucts.

Another object of the invention is to provide a device having the above named characteristics and embodying means whereby the degree of homogenization of the fuel may be varied and the combustible mixture enriched or diluted at the will of the operator.

In addition to the foregoing my invention comprehends improvements in the details of construction and arrangement of parts to be hereinafter more fully described and particularly pointed out in the appended claims.

- In the accompanying drawings in which similar and corresponding parts are designated by the same characters of reference throughout the several views in which they appear:

bustion engine and the application of my invention thereto.

Fig. 2, is an enlarged vertical section taken through a gaseous fuel mixing device constructed after the manner of my invention.

Figs. 3 and 1, are transverse sectional views taken on the lines 33 and l4 respectively of the preceding figure, and

Fig. 5, is a view in vertical section of a modified form of construction.

With reference to the drawings 10 indicates generally the cylinders of a conventional type of internal combustion engine for motor vehicles, motor boats, or the like, 11 indicates the carbureter and 12 theintake manifold.

interposed between the intake manifold and the carbureter, and at the point of connection thereof, which connection is shown disestablished for the purposes of my invention is a casing of my device indicated at 13. This casing is in the nature of a tube, open at either end and externally threaded at i said ends for engagement in the outlet of the carbureter and with the intake of the manifold. This latter connection is established through the medium of a right and left union indicated at 14.

With reference to Fig. 2 of the drawings wherein the construction is set forth in detail 15 indicates a ring or annular member, of which three are provided in the present instance and are disposed transversely within the casing 13 in spaced relation, and cone nected through the agency of connecting strips 16 which extend longitudinally of the casing. Extending longitudinally and centrally through the casing is a rod 17 which extends beyond the extreme outer rings 15 and is supported at said ends within supporting bearings 18 secured to transversely and diametrically extending metallic strips 19 which are formed with bent terminals 20 whereby said terminals may be secured, through the medium of screws or other fastenings to the interior surface of the casing. Each of said rings 15 is designed to support one or more layers of wire fabric or some such foraminous material indicated at 22, which are stretched across the rings to entirely till the space inclosed thereby. Collars 23 are formed upon the central rod 17 at points where said rod passes through for reasons i which are however the wire fabric and to which collars the fabric may be secured thereby forming a rigid structure, the'rings', connecting members, etc., being removable from the casing when the fastenings 21 are withdrawn.

The elements 22 are preferably of wire fabric of fine mesh as the successful operation of this device depends upon the extent to which the current of vaporized fuel is divided and the constituent fuel particles thereof further divided and sub-divided to cause the vapor toapproach a uniform consistency. To this end a plurality of layers of wire mesh are disposed in contact in each ring with the meshes of each layer in overlappingrelation soas to provide a greater obstructionto the passage of vapor therethrough, or in other words to provide a finely porous material. If a wire fabric of relatively or extremely fine mesh is employed, only a single thickness for each ring is necessary, but I have found in practice that the provision of a plurality of layers given above is productive of the best results.

Between adjacent rings 15 I further provide similar rings or annular members 24 provided at diametrically opposite points with outwardly extending trunnions 25 which pass through openings in the walls of the casing whereby the rings may be oscillated to a certain extent. The trunnions are threaded and thumb nuts 26 are applied thereto whereby the rings may be retained in a position to which they are adjusted. In a manner similar to the rings '15, the rings 24 are provided with one or more thicknesses of wire fabric 27 of a degree of fineness corresponding substantially to that of the foraminous elements 22 and are, perforated centrally to receive the rod 17.

When starting an internal combustion engine embodying my mixing device it may be necessary to employ gasolene initially or other volatile combustible, but after the engine has been running for a short time and itscylinders have become heated, the carbureter may be supplied with kerosene and the engine willoperate successfully with this fuel alone. By suitably disposing the rings 27, which are in the nature of porous butterfiy valves, the currents of fuel passing through the device are partly deflected upon contacting with the valves and partly passed through the valves thus permitting and insuring a greater degree of mixture without interrupting the velocity of the vapor currents passing through the device to any considerable extent. The particles of kerosene which form the vapor as it leaves the carloiir'eter, are broken up into finer particles upon passing through the foraminous element and as a result a mixture passes into the manifold which mixture is of a uniform consistency. I have found in practice that vof the appended claims.

if kerosene oilis used as a fuel for internal combustion engines in comiection with a device constructed after the manner of my invention, no great amount of carbonization will take place within the cylinders and the power obtained through the use of this fuel compares favorably with that of gasolene.

In Fig. 5 of the drawings a modified form of my invention is set forth wherein the easing 13 is provided with a plurality of spaced rings 28, all rigidly held in spaced relation through the medium of the connecting strips 16 and a central rod 17. Each of the rings 28 is provided with one or more layers of wire fabric 29 in a manner set forth in connection with the form of my invention first described, and the manner of operation of this form is practically identical with the operation of the other form; the difierence resides merely in the omission of the movable valve like elements and a thorough intermixture of kerosene vapor is obtainable by its use.

Thus it will be seen that I have provided a device which is extremely valuable in that it promotes a considerable saving and economy in the use of fuel for internal combustion engines. The device is moreover ex tremely simple in construction thereby simplifying the operation thereof not to mention the reduced cost of manufacture.

While I have illustrated and-described my invention with some degree of particularity I- realize that in practice various alterations tlie'reover may be made, and I therefore desire to reserve the right and privilege of changing the form of the details of construction or otherwise altering the arrangement of the correlated parts without departing from the spirit ofthe invention or the scope Having thus described my invention what I claim as new and desire to secure by Letters Patent is: 1.
